$Q 5-minute plunge of 1.23%, to 0.1106, with a 24h range of 0.07811 ~ 0.1529.
A move is only valid when volume and price move in sync; an unusual move in a single candlestick doesn't tell us much.
My stance on this kind of sharp drop is: don't catch the first falling knife; wait for confirmation that it has bottomed before reassessing.
